Hermes has, over the ages, moved the location of the datestamps and craftsman's stamp on the bags. Don't go by location as an indication that the bag is fake, otherwise you will drive yourself crazy trying to authenticate Trims and Evelynes. The 10 is the craftsman's stamp. There is no picture of the datestamp so to be certain I would ask for a picture. She says the bag is stamped E, it needs to be in a circle, which would date it to 1974. The hardware stamp, with the Hermes, Paris stacked on top of each other dates this bag to before the early 1970's. The Hermes, Paris, made in France stamp dates this bag to after 1970. It also appears to be a natural stamp, but remember this bag was dyed. The zipper is accurate for this time period. No double ring, no strap. All the hallmarks are there.
